A monkey falling through the jungle reaches out and grabs a horizontal vine to stop his fall. One end of the vine comes loose while the other end remains firmly attached. This causes the monkey to swing in a vertical circle. When the vine is horizontal, the monkey moves at a velocity (v1) of 12 m/s. When the vine is vertical, the monkey is located at a distance (h) that is 1.3 m lower than his original position when he first grabs the vine. What is the velocity (v2) of the monkey at the bottom of his arc?
